From my undertanding the current form of cigarette tobacco is formulated to inhale in order to release the nicotine. My thought though is that this process is a newer one. So when did the norm become to inhale cigarettes and tobacco smoke? I assume that tobacco produced for the pipe has stayed relatively the same over time. Old pipe blends are also advertised as cigarette blends as well. So was there a time where the pipe was also inhaled or was it always assumed that one didn't? I'm also curious if there was indeed a shift, when did it happen?
